VTo all whom it mag/concern.' Y Be it known that I, FRED W. BIRTOH, citizen of the United States, residing at La porte, in theV countyifLaporte and lState'of 5 Indiana, have invented a certain newran] yuseful Improvement (in Valves o r Gras Cocks, of which'theffollowing isv a full, clear, V'con'- cise, and exact? description, reference being hadV to the vaccompanying drawings, lferru- V ing a parteof'thisspeciiication.

The invention A`1 'el"tes` kto valves, or 'gas cocks, adaptedtobe connected'with la' gas ,supply jforV furnishing gasto the burners j of hot water heaters, franges, industrial appliances,V andtherfdevices. f l, The primel bject 'ofthe i vennen i'sjthe .provisionof a construction whereby the dis- Vcharge 'ofthe gas may bev varied' Amdfregulated as desired-without interfering wither i0 changing thenozzle velocity thereof. "By

Ineans of the invention constantglnozzle YQ- locity ofthe .gas may be secured. v It is' another oh'ect of th'. 'nvention to provide 'the r casing of the gasl oock with 'a branch which is constructed in 'Sufh' a Inan- Y Vneras to permit the free`anduno'bstrufcted passage of they gas through it' and' Vvto jlcoustruct a part ofthejbranch in'such a'inanvner that a movablejcap orthi1nblefnayhe adjustably arranged on thebranchfand may n be actuated to cooperate .with the :specially constructed y-branlchto regulate the' Vdischarge vofthe gas throughfsaidV gasicockandtosee 'cure'amaxmum velocity O 'ffgeswenn@ 'to provide a; construction; wherein the 'nurni. her of parts employed'is IQdu'ced toa mini# fmum and which may befrnanufa'ctured ata lowcost. 40 Vjlnthestru gings, the valve casing is provided with' a tubular` projection,V or branch forined'f-to provide ngers which are spaced apart' from eachf other affording', passages for the fgas,

Vits Isothat the gas mayfpassifrom-'thenterier -to the eXterior'c-thetubular portion: e ,TheeXtre'mities f these Yspaced "lingers Vfurthest,awayfrom thema'in lbody of the gas ,cock are all l connected'- togethenfllfdfthis extremity or nozzle` having an aperture` a1"- ranged therein f whichfi's in substantial' .reg-

istry Y and alignment withfthe bore jofthe tubular'extensionor branclLl rial the eture. 'illustrated z in the conical .shaped extremity' or f nozzle, which' isdispos'e'dbetween each of the fingers,-,is cutaway, so thatfthe gas may flowl 4unim- 'peded outwardly "through the cut-,away openings arranged VVimniediately ladjacent the rearofthe lend of Vthe conical .shaped extremity or nozzle. These,- vpreferably ounfspaces between vthe) outer ends of the projections, or' 'inger's, communicate with the gas passage in the interior of the tubular extension' vo r 1hr-anch 'of the valve casing.

The y; 'conical shaped? endfv of 'the tubular branch Preictsa Slight dstahcebeyondthe 'outerfterinination of the;V cutout`openings arranged between each' of the'- ngersand .provdes a seat for an adjustable "cap-v or "thiinble, 4the', inner'end 'fof which Vis screw Y threaded .`and arrangedfupon the tubular` branch. v This thimble ifsjprovid'ed WithV an f aperture which cooperateswithtm 'conical shapeifl "end seat portion' to regulate the flow of gas' through Lsaidg tubular l branch.

4. In a gas regulating valve, the combination of a casing, a. valve arranged in the casing, said casing being provided with an extension having a passage controlled by said valve, the end of the extension being provided with a plurality of separated, sub-V stantially parallel ngers, one end of each of said iingers being connected together'and terminating in a conical shaped end portion,

the conical shaped end portion beingl formedI A ling an aperture Which is arranged in substantial alignment with said valve controlled passage, the material ,ofthe conical shaped portion between 'said lingers being formed to provide a passage, said extension being threaded, a thimble arranged upon Vthe threaded portion, said thimble being adjustable and in spaced relation to the extension,-

'an aperture provided in said thimble, said last mentioned aperture being arranged to cooperate With the conical shaped end porj tion of thev extension to regulate the ovv'of gas through the aperture in said thimble. A

In Witness whereof, I hereunto subscribe 1 FRED W. BIRTCH.
